The stock market ended another see-saw day broadly mixed after a big rally in the morning gave way to a brief drop in the afternoon, the AP reports. Stocks got off to a strong start Tuesday on encouraging news that the US and China appeared to be restarting talks on defusing their trade conflict. Those gains faded and then turned to losses thanks to more declines in banks. Several big technology and health care stocks fared better. Microsoft and Johnson & Johnson each rose 0.9%. The S&P 500 index fell 1 point to 2,636. The Dow Jones Industrial Average fell 53 points, or 0.2%, to 24,370. The Nasdaq composite rose 11 points, or 0.2%, to 7,031. (More stock market stories.)
